First of all, I would like to tell you that I really enjoy this nui. I have been using it for quite a while now and think it's much more convenient than other addons I tried.

I was also very happy to see that it was upgraded for the new patch, so I can continue to use this . I play a demonology warlock and have noticed that I can only see how much demonic fury I have by going over the bar with my mouse (or at least I didn't find any other way, sorry if it is there and I didn't notice it ).

Is there a way of showing the actual number instead of the purple bar? That would be so much easier when I'm trying to track when I can go in and out of meta.

The purple bar is the default frame that blizz use. So, it looks like by default there are no text value displays apart from mouseover like with the health and mana bars which nUI have adjusted to show the values for. It would involve customizing the new special bars to permanently display the text value.

I'll take a look tonight and see how simple that would be. I have a demo warlock so can test that specifically but if it works it should be possible to do it similarly on other bars that aren't easily identifiable.
